Definitions

  • This patent document refers to a constructive provision of mechanical pressure regulator for irrigation systems with the aim of regulating the water pressure at the outlet, and the flow rate, being vital for ensuring the uniformity / quantity of applied water.
  • Such regulators are built to work with fixed pressure, which is individually calibrated at the time of manufacture.
  • the operating principle is based on the force exerted by a spring, on a diaphragm, connected to the plunger, against the pressure of the water leaving the diaphragm.
  • This equipment has several problems related mainly to its manufacture, such as the spring, due to the constructive form, the material used, the number of turns and the repetition in the construction process, which interfere in the final performance of the pressure regulator.
  • the spring needs to be specific in the manufacture of each regulator to generate a specific pressure.
  • the operation of the pressure regulator is based on the fact that the pressure losses in a pipe are determined by the roughness and speed of the water, thus, the possibility of changing the flow rate and consequently the water speed, allows the adjustment of the system's performance as a function of water demand; the device described here, by displacing the plunger creates more or less pressure loss inside the regulator. Said plunger is attached to a diaphragm, which in one of its faces undergoes the strain caused by the water outlet pressure, forcing the plunger to move in order to restrict the water inlet, thus decreasing the outlet pressure.
  • the Pressure Control Chamber On the other side of the diaphragm is the Pressure Control Chamber which, according to the pressure inside it, will exert a counter force, causing the plunger to move in order to release the water inlet. With the regulator running, the the plunger is moved until it finds a position where the water outlet pressure is equal to the pressure in the pressure control chamber.
  • Figure 1 represents the schematic of the constructive arrangement of the mechanical pressure regulator for irrigation systems (10).
  • the constructive arrangement of the mechanical pressure regulator (10) for irrigation systems has the ability to adjust the outlet pressure of the water remotely, through a pilot system activated by air, water, oil, or any other fluid in liquid or gaseous form, as an external pressure reference.
  • Its functional principle, shown in Figure 01, is based on the displacement of the piston (5) which creates greater or less pressure loss inside the regulator.
  • the pressure regulator (10) comprises a plunger (5) with a protuberance connected to one side of a diaphragm (4), in order to allow the plunger (5), which is arranged perpendicular to the diaphragm (4 ), move towards the water inlet, obstructing it.
  • the pressure control chamber (3) filled with fluid is arranged, in order to move the piston (5) in the opposite direction to the water inlet.
  • the pressure regulator (10) operates from the plunger (5), which is perpendicularly attached to a diaphragm (4), so that said plunger (5) is stressed in one of its faces, caused by the pressure of water leaving, forcing the plunger (5) to move in the direction of restricting the entry of water, thus decreasing the outlet pressure.

Abstract

L'invention concerne un régulateur de pression mécanique pour systèmes d'irrigation qui, grâce au déplacement du piston, crée une plus grande ou une plus petite perte de charge à l'intérieur du régulateur, faisant ainsi varier le débit en sortie. Ledit piston est assujetti à un diaphragme qui, sur l'une de ses faces, est soumis à l'effort causé par la pression de sortie de l'eau, forçant le piston à se déplacer dans le sens d'obstruction de l'entrée d'eau, diminuant ainsi la pression de sortie. Sur l'autre face du diaphragme se trouve la chambre de régulation de pression qui, selon la pression intérieure, exerce une force contraire, de sorte que le piston se déplace dans le sens de libération de l'entrée d'eau. En cours de fonctionnement du régulateur, le piston est déplacé jusqu'à une position dans laquelle la pression de sortie de l'eau est égale à la pression dans la chambre de régulation de pression.
